			A sequence is a list of values that are applied to the channel at the same rate 
			as the frame rate, shown in the main window. Default for NTSC is 60 FPS and PAL 
            is 50 FPS.<br>

			The DPCM channel behaves different from the others in the way that samples are 
			used, this tab is used to assign DPCM samples to instruments.<br />
			First load the samples, either directly from &quot;Load sample&quot; where the 
			format must be 1-bit delta PCM, or &quot;Import sample&quot; to import wave-files. (The quality of wave files will decrease significantly 
			when converted to DPCM.)
            The NES can handle a total of 16 kB DPCM samples.<br>
			<br />
			Then select a key in &quot;Assigned samples&quot;-box and select the sample from the 
            drop-down box below. The pitch box&nbsp;sets the&nbsp;pitch for the sample.
            <br />
            The &quot;&lt;-&quot; can also be used to assign samples, and &quot;-&gt;&quot; to remove assigned 
            samples.<br>

            </STRONG>Playing a DPCM sample may decrease the volume level of triangle and 
            noise. If full volume isn&#39;t regained after a sample is finished, use a note stop 
            or the Z-effect in the DPCM channel to restore it.

                place cursor in a VRC6 channel and create a new instrument. The differences are
